Roboform (http://www.roboform.com/) sounds similar to some of the password managers here, but also does form filling. There's also a Robo2Go app that let's you tote your passwords on a USB drive.
The browser integration is really nice in that login fields can be prefilled as you visit different sites.
Also there's a password generator than can be customized for special characters, upper, lower, numbers, length, etc.
You can always do a country lookup from APNIC that will give you all of the IP's assigned to China (or any other country that regional registrar manages).
